Euro-Link NOC Change Management Policy
Scope And Mission
Change Management exists to coordinate and inform customers of all
changes that impact any shared computing system or service under the
direction of the Euro-Link NOC. The overriding goal is to provide a
high level of availability and service to our customers. A definition
of change is "to make different, alter, or modify." Change
Management is the process that protects network services from changes
that are potentially disruptive or have unacceptable risk associate
with them. It is the ongoing process of communicating, coordinating,
monitoring, and scheduling changes to that environment. Change Management
has the responsibility to insure that appropriate documentation, testing,
notification (posting announcement), training (customers and staff),
and recovery procedures are in place for each change requested. All
shared hardware, systems software, application software, or procedural
changes which could impact the Euro-Link environment, and possibly impact
service, are to be presented in Change Management prior to implementation.
The purpose of Change Management is not to question the rationale of
a change, but to insure that all elements are in place, all parties
notified and trained, and the schedule for implementation is coordinated
with all other activities on the Euro-Link network.
Objectives Of Change Management:
- To allow changes while, at the same time, maintain or improve service
stability and availability. To increase the probability of success.
- To reduce or minimize the ratio of changes that need to be backed
out of due to inadequate preparation.
- To ensure that all parties affected are informed of planned changes.
- To provide a record of changes implemented to assist with and shorten
problem determination time.
- To ensure that a technical and management accountability for all
changes is identified.
- To assist with the accuracy of predictions of impact, such as response
time, utilization
- To ensure that all affected parties are not only informed, but necessary
documentation and training is in place prior to the implementation.
